FRANK EDMONDS AND RICHARD ENGBERG, OF ALEXANDRIA, MINNESOTA, ASSIGNORS OF ONE-THIRD TO ANDRINV ANDERSON, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION formng part of Letters Patent No. 418508, dated December 31, 1889.

Application filed May 25, 1889. Serial No. 312,059. (No model.)

To all whom it may concern:

Be it known that we, FRANK EDMONDS and RICHARD ENGBERG, both residents of AleX- andria, in the county of Douglas and State of Minnesota, have invented certain new and useful Inprovernents in Car-Oouplings; and we do hereby declare that the following'is afull, clear, and exact description of the in- Vention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention relates toixnprovements in car-couplers, the main object being to provide means whereby cars may be uncoupled from either side or the top o'f the train; and it consistsin the Construction and novel combination of parts herein after described, illustrated in the drawings, and pointed out in the claims.

In the accompanying drawings, formin g part of this specification, in which like letters of reference indicate corresponding parts, Figure l represents a perspeetive View of one end of a car with a coupler embodying the invention attached. Fig. 2 represents a central vertical lon gitudinal section of the drawhead and attachments. Fig. 3 represents a plan View of the draw-head with the roof removed, and Fig. 4- represents a perspective view of the coupling-pin detached.

Referring to thedrawings by letter, A designates a car, to the end of which is journaled in bearings a, bolted or otherwise Secured to said end, the transverse horizontal shaft B,

provided with the inwardly-standing arms b b at its ends on each side of the car, the outwardly-standing arm b' centrally above the draw-head, and the crank ?3 a suitable distance to one side of the arni b'. Whenthe shaft is in its normal position, the crank b stands Vertically downward and the arm b' horizontally outward. The end of the arin b' is connected by a chain C with the upper end of the coupling-pin, hereinafter described.

D is a lever pivoted centrally in the'bifurcated upper end of the standard d, that -'ises fron the roof of the car near the end thei-cof. The end of the outer arm of the lever Dis connected by a vertical link-rod d' with th crank 17 of the shaft B. i

It is evident from the foregoing description that by means of the lever D the brakenan can lift the linkin the draw-h ead when standing on top of the car, and can do the same on either side of the car by depressing the corresponding arm b.

d is a coiled springwith its ends respectively Secured to the foot of the standard d and the outer arm of the lever D, and servingby its retraction to depress said arm and consequently permit the coupling-pi to fall in the draw-head.

The draw-head E is of ordinary general constru ction and Secured in the ordinary manner to the car-platform, being backed by a spring, as usual.` The root of the draw-head has in it a large opening, which is covered by i a metal plate e, in which is the upper pinopening e', the lower pin-opening 6 being in the floor of the draw-head.

The coupling-pin'F is surrounded near its upper end, below the perforation for the attachment of the chain C, with a flange f, which 'rests on the plate e and prevents the pin from falling too far in the draw-head. At its lower end the coupling-pin is provided with outstandinglateral projections f' f which, when the pin is raised, strike against the inner surface of the plate e and prevent the pin leaving the draw-head.

G is a spring-plate With its outer or front edge secured to the inner surface of the floor of the draw-head, near the front end thereof, and its inner edge, which is free, provided with a short rod g, that stands upward within the draw-head and is surrounded by a re-enforcing coiled spring H, the ends of which respectively bear on the facing surface of the plates e and G. The spring-plate Gr curves inward and downward from its outer fixed edge and approaches the floor of the drawhead near enough to hold the link I, when forced into the draw-head, fiat upon said floor, and consequently in proper position to enter an opposing draw-head when two cars come together.

The coupling-pin is providedin its side facing the car with a notoh f which, when the pin is raised, catches on the adjacent part of the edge of the plate e, the upper part of the pin inclining toward the car and its lower end IOO standing between the plates e and G. hen the cars come together, the jar knoeks the pin out of position, so that it falls and engztges the link.

Having described our invention, We claim 1. In a ear-couple3 the eenbination, with the draw-head E and eoupling-pin F, of the transverse shnft B, providedwith the arms b b' and erank b the chatin C, the lever D, pivoted on the standard d, the link-red (Z and the retraeting eoied spring (Z substantially as described.

2. In a ear-eoupler, the eombination, with th e draw-head E, of the spring-piate having its enter edge Secured to the inner surface of the roof of the draw-head and provided with an upstanding rod or sten on its free inner edge, and the eoiled re-enforeing spring surrounding said red, the spring-pinte curving downward and inward within the draw-head in such mzmner as to hold :in entered link fiat on the floor of the drawdead and in position to enter &11 opposing draw-head, substantiallv as described.

3. Iu :L ear-eoupler, the eonbination, With the draw-head E, of the plate e, having the uppe' pin-hole, the spring-plate &having the red g and opening g', the eoiled spring H, the eoupiing-pin F, having the flmge f, noteh f and projeetions f and mechanisn, substantially as described, Whereby the said pin may be raised and lowered, as specified.

In testimony that We claim the foregoing :s our own We have heteunto affixed our signatures in presence of two witnesses.
